STOCKHOLM, SWEDEN -- (MARKET WIRE) -- February 12, 2007 -- Challenger mobile™
(www.challengermobile.com), a pioneering global telecom service, has
launched a new offering that makes free mobile internet calls available to
people who own a mobile phone that supports internet calls (such as the
Nokia Eseries). When signed up for the service customers can make free
mobile internet calls whenever they are in a WiFi zone.

The service launched in beta in December 2006, setting in motion Challenger
mobile's strategy to bring free internet calls to the mobile telecom
market. Since then, customers in more than 100 countries around the world
have joined and are using the service.

By signing up and then quickly adjusting their phone settings to enable
internet calls, Nokia Eseries owners can easily start making FREE calls.

Carl-Johan Grund, Vice President of Mobile Business Challenger (the company
that offers the service).

"The ability to make free mobile calls whenever in a WiFi zone is
attractive to anyone who uses a mobile phone in their personal and
professional life. The availability of wireless internet in offices for
example, means businesses around the world can instantly experience more
real-time efficiency while also dramatically improving returns on their
investments in technology and telecommunications," Grund concludes.

The company is expected to continue to launch its service on other new
mobile phones that hit the market supporting internet calls. Anyone who is
